Tableau SCA-C01 Exam With Confidence Using Practice Dumps

Tableau Server’s minimum hardware recommendations for a production single-node deployment ensure reliable performance for small to medium workloads. As of the latest documentation:

CPU: 8 cores (2.0 GHz or higher) to handle concurrent users, rendering, and background tasks.

RAM: 32 GB to support in-memory processing (e.g., VizQL, Data Engine) and caching.

Disk Space: 50 GB free for installation, logs, extracts, and temporary files.

Let’s break it down:

Option C (8-Core CPU, 32 GB RAM, 50 GB free disk space): Correct. This matches Tableau’s official minimum for production:

8 cores ensure sufficient parallelism for processes like Backgrounder and VizQL.

32 GB RAM supports multiple users and extract refreshes.

50 GB disk space accommodates growth (initial install is ~1–2 GB, but logs and extracts expand).

Option A (4-Core, 16 GB RAM, 50 GB): Incorrect. Too low for production—4 cores and 16 GB RAM are below the threshold for reliable performance under load.

Option B (2-Core, 8 GB RAM, 15 GB): Incorrect. This is for non-production (e.g., trial) setups, insufficient for production stability.

Option D (4-Core, 64 GB RAM, 50 GB): Incorrect. 4 cores are inadequate, though 64 GB RAM exceeds the minimum (32 GB).

Why This Matters: Under-spec hardware can lead to slow performance, failed refreshes, or crashes in production—adhering to the minimum ensures stability.

Tableau Server’s user-based licensing model assigns licenses to individual users (Creator, Explorer, Viewer) rather than machines or cores. Key features include:

Subscription license: Licenses are typically subscription-based, renewed annually or monthly, aligning with Tableau’s pricing model.

Distinct user roles: It supports three roles (Creator, Explorer, Viewer), each with specific capabilities, enabling granular access control.

Option A (A subscription license): Correct. User-based licenses are subscription-based by default.

Option B (Enables distinct user roles): Correct. The model defines Creator, Explorer, and Viewer roles.

Option C (Restricts the number of machine cores): Incorrect. This applies to core-based licensing, not user-based.

Option D (A perpetual license): Incorrect. Perpetual licenses were phased out; user-based licenses are subscription-based as of recent models.

Data-driven alerts notify users when data meets conditions (e.g., sales > $10K). Let’s examine when Tableau checks these:

Alert Mechanics:

Enabled per site (Settings > General > Data-Driven Alerts).

Backgrounder evaluates conditions against extract data.

Check Intervals: Configurable via tsm configuration set -k dataAlerts.checkIntervalInMinutes (default: 60 minutes).

Refresh Trigger: Also checks post-extract refresh for immediate updates.

Option A (Every 60 minutes): Correct.

Details: Default interval—Backgrounder polls every hour to evaluate alert conditions.

Config: Adjustable (e.g., -v 30 for 30 minutes).

Option D (Whenever extracts in the related workbook are refreshed): Correct.

Details: An extract refresh updates the data, triggering an immediate alert check to catch changes promptly.

Why: Ensures timely notifications without waiting for the next poll.

Option B (Every 10 minutes): Incorrect.

Why: Not the default—possible via config, but not standard.

Option C (Whenever a new extract is published): Incorrect.

Why: Publishing creates the extract; alerts trigger on refreshes or polling, not initial publication.

Why This Matters: Timing affects alert responsiveness—balancing frequency and server load is key.
